Evidently, all customer-facing channels such as Banking and FinTech continue to undergo rapid changes due to digitization, and the need for effective testing has increased manifold to enable stable products. Especially for banking applications, it is critical to have high-performing apps, as they tend to serve millions of transactions. Importantly, there are certain characteristics with respect to banking applications that require deep analysis to enable stable and high-performing apps.

Banking applications should be able to deliver safe and secure transactions, for which effective end-to-end software testing of their systems is required. It should be taken up using various types of software testing methods to ensure defect-free applications. Moreover, as the banking software applications are complicated with many dependencies, thus the testing process requires more time and a complete understanding of the scope.

1. Regulation & Compliance:

There is an increased focus on business transparency globally and there is a strong need to abide by certain regulatory compliance terms. Hence, efficient software testing is required to suffice various open banking API terms and conditions.

2. Digital Convergence:

Digitalization has brought in a paradigm shift in the banking services domain with the emergence of smartphones, tablets, and IoT based devices. The digital payments have eased the transactions to paperless currency for which end-to-end testing is utmost required.

3. Enhanced User Experience:

Today, users are tech-savvy with ever-changing customer expectations. The customer experience (CX) is at the heart of any business. There is more emphasis laid on application aspects such as usability, great user interface (UI) and stable performance at peak loads. In order to achieve all these intricate features, effective usability testing along with end-to-end performance testing is required to deliver great user experience (UX) and flawless performance.

4. Stable Transactions with Payment Integrations:

Banking apps require a stable payment gateway integrations to ensure effective transactions to customers. To achieve this, effective software testing is necessary.

5. Security and Privacy:

For all banking applications, the topmost priority is to safeguard the customer’s critical data and ensure safe transactions. With the cyber-attacks being rampant, it is important for banking applications to undergo vigorous security testing to protect and deliver a secure environment for customer transactions.

6. Emergence of New technologies:

In order to reach more customers quickly, mobile banking has evolved in a large way with voice recognition apps and browser service applications. These apps should be thoroughly tested before going live to the market to ensure a flawless experience.

What are the Steps Involved in Banking App Testing?

Segregation of Data: The initial step in banking app testing is to perform research by gaining domain knowledge and understanding the expected industry standards.

Identification of the required tests: Based on the research performed, test requirements are implemented to meet the functional and business goals.

Creation of banking app test cases: An online banking application test suite is created based on the aspects of application’s performance, user experience, functionality, and security aspects.

Implementation of Functional testing: Testing activities such as test case review, test case execution, and test case preparation are run to validate and check whether the required functionalities are met as expected or not as outlined in the requirements document.

Validation of Database Structure: Data should be stored in an easy and structured format and follow the mechanism of data restoration.

Data Encryption and Authentication: User Authentication and data encryption are assessed to ensure no data breach is reported in the banking app. In order to achieve this, banks are required to implement a multi-layer validation process, such as OTP or One Time Password. Automation tools like HPWebInspect and IBM App Scan can be used to perform security testing; and for manual testing tools like HTTP watch, Proxy Sniffer, Paros Proxy, etc. can be used.

Examination of App Usability: In order to ensure the app usability for all, tests are performed to examine how easy is the app usage across its system

Validation of App Performance: The banking apps are monitored to check the app performance and the speed for loading the page across various browsers.

Confirmation of User-Acceptance: With a constant testing practice, the performance of the banking application is monitored to confirm the app is error-free and meets the required user-acceptance. Also, it is the last stage of testing performed by the end-users by considering the real-world scenarios.


Banking applications are critical as they are directly linked to customers and involves millions of transactions. Hence, testing these applications is critical and various methods of software testing such as load/performance testing, security testing, usability testing and functional testing should be taken up to ensure bug-free, fully functional and high-performing applications.
